Assuming there are no unexpected incidents, if Zhou Tian continues to attack in this way, all the territories of the NPCs would likely soon fall into his hands. Contemplating the potential fate awaiting them, the NPCs could not help but panic.
Despite knowing the temperament of the goblins, when pushed to an existential crisis by Zhou Tian, the desperate NPCs finally sent envoys hoping to garner the support of the goblins.
The outcome, however, was not beyond the expectation of the NPCs and Zhou Tian.
Goblins are not a race with a long-term perspective. One can say that except for their research and development abilities, which surpass other races, the goblins can be deemed deficient in everything else. Because of the goblins' nature, they could also not possess the same foresight as the NPCs.
